WATER METER.

Application filed July 12, 1920. Serial No. 395,809.

(GRANTED THE PROVISIONS 0F THE ACT 0F MARCH 3, 1921, 41 STAT. L., 1313.)

To all whom it may concern."

Be it known that I, ANTOINE JOSEPH As TIER, a citizen of the Republic ofFrance, residing at 130 Boulevard Valmy, 1n Colombes, Seine, France,have invented new and useful Improvements in Water Meters "(for which Ihave filed application for Letters Patent of France March 8, 1919, No.496,764), of which the following is a speciication. l

This invention relates to a proportional meter foreonduits or pipes forwater or other fluids, characterized by its simplicity of construction,facility of installation, the small loss of heat that it causes in thepipe in which it is installed, and the possibility which it offers ofremoving the counting device without interruptingthe circulation ofwater in the pipe.

To make the invention clearly understood, the present specification isaccompanied, merely by way of example, by a drawing in which v Figure 1is a transverse sectional view o my improved meter.

Figure 2 is a sectional view of the same taken on the plane indicated bythe line 2-2 of Figure 1.

Figure 3 is a fragmentary longitudinal section taken on the planeindicated by the line 3 3 of Figure'l, and showing the part 11 in oneposition.

Figure 4 is a similar view showing the part 11 in another position.

In the said drawing 1, is the body of the meter; it is provided with twoiianges 2 intended for connecting it to the pipe on which it is to beinstalled and it has a lower chamber 3 separated from the upper chamber4 by a removable semi-circular partition 5 which rests on a shoulder 6provided in the body of the meter.

The artificial resistance is created in the chamber 3, tending' toreduce the quantity of water which flows therethrough. This resistanceis formed by a spiral screw 7 which is fixed in position and whosepresence causes the reduction of the traversing quantity sov that in theupper chamber 4 a larger quantity is diverted therethrough in pro ortionto the ratio of unoccupied space in t e chambers 3 and 4.

- For the purpose of introducing the semicylindrical partition 5 and thesection of Archimedes screw 7, the apparatus is provided at its upperpart with a preferably rectangular opening closed by a covcr 8 providedat the bottom with a cylindrical wall 9, as Well as with four divergentflanges 10 startin from openings 9a.', 9b in opposite sides of the saidwall 9, as more particularly clearly shown in Figures 3 and 4, the saidwall 9'. being here shown as integral. with the semi-cylindricalpartition 5.

The openings 9a, 9b are respectively inlet and outlet openings and thewalls or flanges 10 serve to direct water through the pass formed by thechamber within the wall 9 and to also facilitate the -discharge of waterthrough said pass.

A sleeve 11 which forms a casing is mounted with a slight amount offriction within the wall 9, and its penetration into the latter islimited by an annular fiange 12 with which it is provided on its outercircumference and which comes into contact with a seat provided in thesaid wall 9. A packing ring 19, a bronze ring 13 and a nut 14 screwedinto the-boss 15 of the cover 8, ensure the proper positioning of thesleeve llrelatively to the wall 9.

An inner annular flange 16, with which the sleeve 11 is provided in theinterior, forms a bearing for the wheel gear train of any well knownconstruction of the meter, the small turbine or vane wheel 17 of whichis mounted in a transverse chanel in the lower part of the said sleeve11. Said sleeve has openings which are adapted to register with thoseprovided between the diverging partitions 10 hereinbefore mentioned.

The upper end of the sleevev 11 is closed by a screw cover 18a with awindow 18 having a glass cover through which the indications of thewheel gear train can be read.

My vimproved meter may be arranged in any desired position for use butowing to the arrangement of the baille screw 7 the flow of the liquid isretarded through the cham' stop the How in the pipe.

. cient to unscrew slightly the nut 14 in order to be able to give aquarter turn to the sleeve 11, so that it will be caused to close theopenings between the wall 9 which form'for it a cock casing. The cover18a is then removed, when the Wheel gear train may be Withdrawn.

The cover 18a can be afterwards replaced until the Wheel gear train isto be reinstated.

Having thus described my inyention, I claim: L

l. In a fluid meter, a bodyhaving a pass therethrough for the flow of"fluid and also having a second pass parallel with the first named passand provided with Walls forming a cylindrical chamber intermediate theends of said second pass, an Archimedean screw arranged in the firstnamed pass, a cylindrical casing arranged and mounted for turningmovement in said chamber of the second pass and having a Wall providedwith openings which by the turning of said casing may be caused toregister with the second pass or to be moved out of communicationtherewith to cut off the flow of fluid through said second pass andfluid operated measuring means mounted in said casings.

2. In a iluid meter, a body' having a pass therethrough for the flow offluid and also havin a second pass vparallel with the first name passand provided With vvalls forming a c lindrical chamber intermediate theends o said second pass, an Archimcdean screw arranged in the firstnamed pass, a cylindrical casing arranged and mounted for turningmovement in said chamber in the second passl and having a Wall providedwith openings Which by the turning of said casing may be caused toregister with the second pass or to be moved out of communication:therewith to cut off the flow of fiuid through said second pass andfluid operated measuring means mounted in said casing and removabletherefrom, said casinghaving a removable cover laffording access to saidmeasuring means, and 4means to secure said casing in either position.

In testimony whereof I aiix my signature.

ANTOINE JOSEPH- ASTIER.
